A system for lip retraction and aerosol reduction, including a mouthpiece with an integrated single-lip retractor and aerosol suction head, single-lip internal retentive wings and external retentive wings configured to support and secure the mouthpiece in a mouth of a patient, and comfort retention notches formed between the internal retentive wings and external retentive wings to enhance comfort of the patient and to secure the mouthpiece in the mouth of the patient. The system includes a High-Volume Evacuator (HVE) valve stem configured for attachment to an HVE suction tube to provide suction for the aerosol reduction.

A disposable dental aerosol device has a tube having a tip end having a tip having a tip opening, a valve receiving end having a rear end opening, and an aerosol directing device having an aerosol collecting funnel, a first vane, a second vane, a first aerosol capturing port formed between the first vane and the second vane, and a second aerosol capturing port formed between the second vane and the first vane.

An evacuation dam apparatus including a frame having a top frame member, a bottom frame member, and two side frame members. A working area formed by the frame, a plurality of ports adjacent the working area, an outlet fluidly coupled with the plurality of ports. A fluid flow from at least a portion of the plurality of ports to the outlet forms a fluid flow path across the working area and at least a portion of the fluid flow path is formed within the frame.
